A bracket configured to mechanically couple an actuator an accessory component. The bracket may be mounted relative to the accessory component, and the bracket may allow the actuator to be mounted without the use of tools. The bracket may also allow the actuator to be mounted in each of two or more orientations such that the actuator is able to drive the accessory component in each of two directions, depending on the mounting orientation.

The disclosure relates to a Demand Control Ventilation (DCV) and/or Economizer system that is capable of drawing outside air into an HVAC air stream. In some instances, the DCV and/or Economizer system may be configured to help perform one or more system checks to help verify that the system is functioning properly. In some instances, the DCV and/or Economizer system may provide some level of manual control over certain hardware (e.g. dampers) to help commission the system. The DCV and/or Economizer system may store one or more settings and or parameters used during the commissioning process (either in the factory or in the field), so that these settings and/or parameters may be later accessed to verify that the DCV and/or Economizer system was commissioned and commissioned properly.

Demand control ventilation system with commissioning and checkout sequence control

A mechanism for compensating power to a motor or actuator. Compensation may counter the effects of changing voltage levels of power to the motor and varying temperatures at the motor. An output of a wave generator may be input to a comparator along with a level of voltage representing the temperatures and voltage levels. An output may be a power signal for driving the motor at a constant speed and/or torque which can increase a maintenance-free lifetime of the motor and actuator.

Power supply compensation for an actuator

A system for controlling power to actuators. For example, a controller may output a signal having a variable duty cycle waveform for controlling current to an actuator via an interface circuit between the controller and the actuator. Changing the duty cycle may change the amount of current to the actuator. The controller may provide a control signal that optimizes power consumption by the actuator for efficiency purposes. However, if the controller fails, then no control signal may be available to allow current to the actuator, particularly in situations where the actuator may need to be operationally tested. To avoid such situations, fail-safe bypass switching may be incorporated into the interface circuit. Upon absence of a control signal from the controller, the circuit may provide a default signal in lieu of the control signal to maintain current to the actuator.

An actuator includes a mechanical transducer component capable of applying a mechanical force to an external object in response to electronic signals. The actuator includes a communications interface capable of wirelessly receiving configuration data related to operation of the actuator. A settings module is coupled to the communications interface and capable of storing the configuration data. A controller unit is coupled to the mechanical transducer and the settings module. The controller unit is capable of determining the configuration data via the settings module and controlling the mechanical transducer in conformance with the configuration settings.

Wireless actuator interface

A system for maintaining appropriate control of an actuator in the event of a power disruption without being adversely affected by the period of the power disruption. The actuator may close during the power disruption but will be fully opened upon the return of power to the system. After being opened, the actuator may be kept open with less power than needed for opening it.
